iOS开发项目篇—29自定义工具条

一、简单说明

1.实现效果：

2.实现思路：

（1）尝试：

 1 //添加子控件
 2 -(void)setupTextView
 3 {
 4     //1.创建输入控件
 5     YYTextView *textView=[[YYTextView alloc]init];
 6     //设置frame
 7     textView.frame=self.view.bounds;
 8     [self.view addSubview:textView];
 9     self.textView=textView;
10     
11     //2.设置占位文字提醒
12     textView.placehoder=@"分享新鲜事···";
13     //3.设置字体(说明：该控件继承自UITextfeild，font是其父类继承下来的属性)
14     textView.font=[UIFont systemFontOfSize:15];
15     //设置占位文字的颜色为棕色
16     textView.placehoderColor=[UIColor lightGrayColor];
17     
18     //4.设置键盘顶部的工具条
19     textView.inputAccessoryView=[UIButton buttonWithType:UIButtonTypeContactAdd];
20 }

（2）实现方案

自定义一个继承自UIView的类，实现工具条。在View的内部添加五个按钮。

导入图片素材

二、实现

1.搭建toolbar

YYComposeToolBar.m文件

 1 //
 2 //  YYComposeToolBar.m
 3 //
 4 
 5 #import "YYComposeToolBar.h"
 6 
 7 @implementation YYComposeToolBar
 8 
 9 - (id)initWithFrame:(CGRect)frame
10 {
11     self = [super initWithFrame:frame];
12     if (self) {
13         //设置工具条的背景图片
14         self.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageWithName:@"compose_toolbar_background"]];
15         
16         //添加所有的子控件
17         [self addButtonWithIcon:@"compose_trendbutton_background" highIcon:@"compose_trendbutton_background_highlighted" tag:YYComposeToolbarButtonTypeTrend];
18         [self addButtonWithIcon:@"compose_camerabutton_background" highIcon:@"compose_camerabutton_background_highlighted"tag: YYComposeToolbarButtonTypeCamera];
19         [self addButtonWithIcon:@"compose_toolbar_picture" highIcon:@"compose_toolbar_picture_highlighted" tag:YYComposeToolbarButtonTypePicture];
20         [self addButtonWithIcon:@"compose_emoticonbutton_background" highIcon:@"compose_emoticonbutton_background_highlighted"tag: YYComposeToolbarButtonTypeEmotion];
21         [self addButtonWithIcon:@"compose_mentionbutton_background" highIcon:@"compose_mentionbutton_background_highlighted" tag:YYComposeToolbarButtonTypeMention];
22     }
23     return self;
24 }
25 
26 /**
27  *  添加一个按钮
28  *
29  *  @param icon     默认图标
30  *  @param highIcon 高亮图标
31  */
32 - (void)addButtonWithIcon:(NSString *)icon highIcon:(NSString *)highIcon tag:(HMComposeToolbarButtonType)tag
33 {
34     UIButton *button=[[UIButton alloc]init];
35     [button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
36     [button setImage:[UIImage imageWithName:icon] forState:UIControlStateNormal];
37     [button setImage:[UIImage imageWithName:highIcon] forState:UIControlStateHighlighted];
38     [self addSubview:button];
39 }
40 -(void)buttonClick:(UIButton *)button
41 {
42     YYLog(@"%@--",button);
43 }
44 
45 -(void)layoutSubviews
46 {
47     [super layoutSubviews];
48     int count=self.subviews.count;
49     
50     CGFloat buttonW=self.width/count;
51     CGFloat buttonH=self.height;
52     for (int i=0; i<count; i++) {
53         UIButton *button=self.subviews[i];
54         button.y=0;
55         button.width=buttonW;
56         button.height=buttonH;
57         button.x=i*buttonW;
58     }
59     
60 }
61 
62 @end

YYComposeToolBar.h文件

 1 //
 2 //  YYComposeToolBar.h
 3 //  22-微博自定义工具条
 4 //
 5 
 6 #import <UIKit/UIKit.h>
 7 
 8 @interface YYComposeToolBar : UIView

10 //使用枚举

12     YYComposeToolbarButtonTypeCamera, // 照相机

14     YYComposeToolbarButtonTypeMention, // 提到@
15     YYComposeToolbarButtonTypeTrend, // 话题
16     YYComposeToolbarButtonTypeEmotion // 表情
17 } YYComposeToolbarButtonType;
18 
19 @end

YYComposeViewController.m文件

 1 //
 2 //  YYComposeViewController.m
 3 //
 4 
 5 #import "YYComposeViewController.h"
 6 #import "YYTextView.h"
 7 #import "YYComposeToolBar.h"
 8 
 9 @interface YYComposeViewController ()
10 @property(nonatomic,weak)YYTextView *textView;
11 @end
12 
13 @implementation YYComposeViewController
14 
15 
16 - (void)viewDidLoad
17 {
18     [super viewDidLoad];
19   
20     //设置导航栏
21     [self setupNavBar];
22     
23     //添加子控件
24     [self setupTextView];
25     
26     //添加工具条
27     [self setupToolbar];
28     
29 }
30 
31 -(void)setupToolbar
32 {
33     //1.创建
34     YYComposeToolBar *toolBar=[[YYComposeToolBar alloc]init];
35     toolBar.width=self.view.width;
36     toolBar.height=44;
37     
38     //2.显示
39     self.textView.inputAccessoryView=toolBar;
40 }
41 //添加子控件
42 -(void)setupTextView
43 {
44     //1.创建输入控件
45     YYTextView *textView=[[YYTextView alloc]init];
46     //设置frame
47     textView.frame=self.view.bounds;
48     [self.view addSubview:textView];
49     self.textView=textView;
50     
51     //2.设置占位文字提醒
52     textView.placehoder=@"分享新鲜事···";
53     //3.设置字体(说明：该控件继承自UITextfeild，font是其父类继承下来的属性)
54     textView.font=[UIFont systemFontOfSize:15];
55     //设置占位文字的颜色为棕色
56     textView.placehoderColor=[UIColor lightGrayColor];
57     
58 }
59 
60 //设置导航栏
61 -(void)setupNavBar
62 {
63     self.title=@"发消息";
64     self.view.backgroundColor=[UIColor whiteColor];
65     self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@"取消" style:UIBarButtonItemStyleBordered target:self action:@selector(cancel)];
66     self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@"发送" style:UIBarButtonItemStyleBordered target:self action:@selector(send)];
67     self.navigationItem.rightBarButtonItem.enabled=NO;
68 }
69 
70 -(void)send
71 {
72     YYLog(@"发送----");
73 }
74 
75 -(void)cancel
76 {
77 //    [self dismissViewControllerAnimated:YES completion:nil];
78     self.textView.text=@"测试";
79 }
80 @end

实现效果：

打印查看：

2.设置代理，监听按钮的点击事件

获取按钮的几种方式：

此处通过给button设置tag，而tag定义为枚举。

优点：不论添加按钮的顺序如何改变，程序都不会出错，而且可读性好。

1 //使用枚举
2 typedef enum {
3     YYComposeToolbarButtonTypeCamera, // 照相机
4     YYComposeToolbarButtonTypePicture, // 相册
5     YYComposeToolbarButtonTypeMention, // 提到@
6     YYComposeToolbarButtonTypeTrend, // 话题
7     YYComposeToolbarButtonTypeEmotion // 表情
8 } YYComposeToolbarButtonType;

实现代码如下：

11     YYComposeToolbarButtonTypePicture, // 相册
12     YYComposeToolbarButtonTypeMention, // 提到@
13     YYComposeToolbarButtonTypeTrend, // 话题
14     YYComposeToolbarButtonTypeEmotion // 表情
15 } YYComposeToolbarButtonType;
16 
17 @class YYComposeToolBar;
18 @protocol YYComposeToolBarDelegate <NSObject>
19 
20 -(void)composeTool:(YYComposeToolBar *)toolbar didClickedButton:(YYComposeToolbarButtonType)buttonType;
21 
22 @end
23 @interface YYComposeToolBar : UIView
24 @property(nonatomic,weak)id<YYComposeToolBarDelegate> delegate;
